The Australian Burden of Disease Study 2018 provides updated estimates for over 200 diseases and injuries in Australia for 2018, 2015, 2011 and 2003. Burden of disease measures the impact of living with illness and injury and dying prematurely. The summary measure ‘disability-adjusted life years’ (or DALY) measures the years of healthy life lost from death and illness.
The most recent available burden of disease data for the Australian population are presented in Australian Burden of Disease Study: impact and causes of illness and death in Australia 2018. There is also a Summary report and Key findings report. Detailed estimates from the Australian Burden of Disease Study 2018 can be found under Disease burden: interactive data and Risk factors: interactive data.
Burden of disease estimates for the Aboriginal and Torres Strait Islander population are presented in Australian Burden of Disease Study: impact and causes of illness and death in Aboriginal and Torres Strait Islander people 2018, along with a Summary report and Key findings report. The detailed results can be explored at Disease burden among Aboriginal and Torres Strait Islander people: interactive data and Risk factor burden among Aboriginal and Torres Strait Islander people: interactive data.
As this study (ABDS 2018) provides estimates of disease burden for the 2018 reference year, estimates of the burden due to COVID-19 are not included. However, as part of a separate project, AIHW calculated estimates of the fatal and non-fatal burden due to COVID-19 in Australia for 2020. These estimates have been published in a synthesis report on the direct and indirect health effects of COVID-19 in Australia.
The Australian Burden of Disease Study undertaken by the AIHW provides information on the burden of disease for the Australian and Aboriginal and Torres Strait Islander populations. The study builds on the AIHW's previous burden of disease studies and disease monitoring work and provides Australian-specific estimates for more than 200 diseases and injuries, grouped into
17 disease groups, for 2003, 2011, 2015 and 2018. It also provides estimates of how much of the burden can be attributed to various risk factor exposures, such as tobacco use and overweight (including obesity).
The summary measure of burden of disease analysis is the DALY. One DALY is one year of 'healthy life' lost due to illness and/or death. The more DALY associated with a disease or injury, the greater the burden. DALY are estimated for every occurrence of every disease and then added together for the whole population, to indicate the total disease burden. The DALY is produced by combining the non-fatal and fatal burden together. People generally experience more burden as they age.
Non-fatal burden is expressed as years lived with disability (YLD). YLD measures the proportion of healthy life lost due to living with a disease in a given year, and is influenced by the number of people with each disease, how long they spend living with it and how severe the effects are.
Fatal burden, expressed as years of life lost (YLL), measures years lost between the age at which a person dies and the number of years they could have potentially gone on to live, based on the current best life expectancy across the world.
The attributable burden is the amount of burden that could be avoided if the risk factor were removed. The risk factors analysed in the study were selected because they are modifiable, with strong evidence that they are linked to diseases that occur in Australia. While it is an extensive list, it does not cover all potential risk factors.
Information on the health impacts and distribution of different diseases, injuries and risk factors is important for monitoring population health and providing an evidence base to inform health policy and service planning. Burden of disease information can also be used to measure the health impact of interventions, and to highlight which diseases or risk factors to focus on when investigating the cost-effectiveness of programs and interventions.

Risk factors contributing the most burden were tobacco use and overweight (including obesity)
13% reduction in total burden rates between 2003 and 2018
The lowest socioeconomic group experienced a burden rate that was 1.6 times that of the highest socioeconomic group
The rate of burden in Indigenous Australians decreased by 15% between 2003 and 2018
Indigenous Australians lost almost 240,000 years of healthy life due to illness and injury in 2018
Indigenous Australians born in 2018 could expect to live around 80% of their life in full health
